Abstract
    The pilargid polychaetes Sigambra tentaculata and S. parva, to date considered synonyms, are redescribed from the examination of type material and additional specimens from the East coast of the U.S.A., and the Atlantic and Mediterranean coasts of Spain. The presence of tooth-like papillae on the proboscis of both species, which is revealed as a character with high taxonomic relevance, is confirmed, as well as the possession of a dorsal row of peristomial papillae and pectinate neurochaetae. Both species are morphologically very closely related but they show clear differences in the arrangement and number of papillae and tooth-like papillae on the proboscis. S. parva is re-established as a valid species.
